Re: Tamiya primer (was [RealSTMFC] Painting brass)

Ok, thanks! I may have been too far from the work. The paint I used is the
"fine surface primer".
But I should say that the powder residue was all over
the booth but not on the model pieces - I was mass painting Athearn blue box
underframes. :-[

Tim, you’re used the wrong primer. You need Tamiya FINE Light Gray Primer. Tamiya also makes a Light Gray Primer, and the cans look alike except for the word FINE. That makes all the difference in the world. Also, it sounds like your spray distance was too far and the paint evaporated before it hit the car. Tamiya paint is highly volatile. The can recommends 8-10 inches from the work, which is closer than most rattle cars. You want to apply paint in 3-5 passes from different angles, especially on SS cars, stock cars, reefers, or any other cars with raised details. Each pass should be slightly wet. Don’t worry about obscuring details, as it dries very fast and very thin. I use paint handles designed by Pierre, and I start with the underframe from all angles until it’s covered, then I do the sides, ends, and roof, in that order. Don’t try to do the whole car at once. Tamiya recommends temperatures above 50° F and avoid use on days where humidity is high. I’ve primed something like 100 car using Tamiya Fine Light Gray primer without any problems.

The other day I tried Tamiya Primer Grey from the can, instead of an airbrush. I was
rather surprised that the paint's color pigment left a POWDER RESIDUE when the carrier
or thinner had evaporated. I actually scooped up a little pile of powder with a stiff
piece of cardstock - it had the exact same consistency as weathering powders that I have!

I have NEVER seen a paint of any type do this before.

Am I doing something wrong? I rarely use spray cans...

P.S. Temperature in my workshop about 66F and low humidity (normal for NE winter)

   Clark, I almost always use a light gray primer, sometimes even from a rattle can, but with good paint, such as Tamiya. And I let it sit for some time to be ENTIRELY dry.
